Okay, let’s tackle this. So Constantine has 42 years of experience as an architect and planner, which is extremely extensive. He’s the owner of his own practice, which suggests he’s self-employed. Location is Royal Oak, Michigan, which is a mid-sized city. The AIA (American Institute of Architects) is a professional organization for architects, and its members typically charge higher rates. However, Constantine’s experience and self-employment status suggest a lower rate. Considering the average hourly rate for architects in the US is around $75-$150, and Constantine’s extensive experience, I’ll estimate around $125 per hour.
